 As promised, we're going back to the basics with the ARS's Dr. Randy Anderson, who discusses his spiral of soil regeneration. And in the next three videos, Dr. Anderson provides the most tangible and straightforward unpacking of the concepts and benefits of soil health, which begin with... No till. So let's get out of the way. One of the things that Dr. Duane Beck recommended was that I speak to you a little bit about this spiral of soil regeneration, so I'd love you to tell us about where it comes from and what it is. Okay, well where it comes from is I was involved in research in the semi-urid regions out of the Great Plains. And when we started No Till, even for us scientists, it was difficult to recognize all the interactive biological factors. And so I was trying to think of how I could tie them together or lay them together. When we started No Till, of course, one of the goals was to maintain the residue on a soil surface to minimize erosion and then also increase the amount of water storage. We started to notice that we were getting a lot of additional benefits. And so I developed a spiral of soil regeneration. What I saw is as we kept, as we moved up with time, we kept gaining more benefits. Our spiral kept getting wider, and so I was trying to show this visually to understand for myself what are these factors, and so therefore I developed a spiral of regeneration. What stimulated me to even think about the spiral approach was this relationship we saw here. When the producers first started No Till, and of course they were maintaining the residues on the soil surface, they were increasing the soil water storage from precipitation because the greater residue, the more effective it is. Because we had more water, we were getting more crop growth. Because we had more crop growth, we were getting more residues, then therefore getting more water. And it seemed like we were developing a spiral here of continuously improving with time. This led me to consider what I referred to as a spiral of regeneration. We started with No Till and Crop Residue. Because we had more soil water, we could have more diversity in our rotations. This led us to gain a wide suite of benefits here. Stay with us as Dr. Anderson walks us through the benefits of soil health. See you soon.
